BUCKLE.

Specification of Letters Patent.

Application filed September 5, 1914. Serial No. 860,404.

To all 't0/1.0m it may concern:

Be it known that I, ELIZABETH LANGEN- Baci-I, a citizen of the United States, residing` at Orlando, in the county of Orange and State of Florida, have invented certain new and useful Improvements in Buckles, of which the following is a specification, reference being had to the accompanying drawings.

My invention relates to certain new and useful improvements in buckles and particularly in buckles designed for use in connection with the straps employed to prevent breakage of automobile springs.

I have found from eXperience that where the ordinary roller buckle is employed that after a very limited use thereof the tongue of such buckles tear the straps and render the same useless. The reason for this is that in this form of buckle the strap on each side of its point of engagement with the tongue of the buckle extends approximately in one plane and beneath the cross bar of the buckle so that all strain placed upon the strap, (and straps for automobile springs are always placed under great strain) causes the strap to pull in a straight line upon the tongue and causes the tongue thereby to tear out the perforation in the strap into an elongated slit thus slackening the strap from time to time and in a vshort time damaging it to an extent which will render it of little value.

My invention has for its object the production of a buckle designed to overcome this diiliculty and one which will not injure the straps even with long continued use, and with this end in view my invention consists in the particular construction hereinafter fully set forth.

In order that those familiar with this art may know how to make and use my improved buckle and appreciate its advantages l will proceed to describe the same referring by numerals to the accompanying drawing in which- Figure 1 is a perspective view of a buckle embodying the features of my invention, andFig. 2 is a central longitudinal section with one end of a strap secured to same threaded in the buckle.

Similar reference numerals indicate like parts in both iigures of the drawing.

l. l. are the side bars of the buckle, 2. 3. are the end bars and 4. 5. are the cross bars intermediate the end bars. rl`he side bars adjacent to each end are turned upwardly at a right angle as shown at 6 so that the end bars 2. 3. occupy a position above and parallel with the side bars as clearly shown. The buckle tongue 7 is vibratively connected with the cross bar 4L and with its free end adapted to contact with the upper surface of the cross bar 5. @ne end of a strap 8 passes around the cross bar a and is riveted to the body of the strap as shown at 9, or secured thereto in any other suitable manner; the strap passes under the end bar 2 which being disposed above the side bars 1. l. provides ample space fer the passage of the strap. After the strap has been passed around any body, or parts to be bound thereby the free end is passed over the raised end bar 3, under the cross bar 5, threaded over the free end of the tongue 7 and then under the raised end bar 2 all as clearly shown in Fig. 2. The fact of the end bar 2 being raised above the side bars permits the strain exerted upon the cross bar a to be in the plane of the side bars, while the fact of the free end of the strap passing over the raised end bar 3 and under the cross bar 5 and threaded over the tongue 7 produces a vertical strain upon the tongue and holds it down tightly against the cross bar 5 so that the strap does not exert the usual straight strain upon the tongue which tends to tear the strap and the raised end bar holds the strap firmly against the under side of the cross bar 5 and holds the tongue immovably. In other words, the free end of the strap after it is engaged by the tongue 7 of the buckle extends over the cross bar 5 and then is deflected downward and cramped over the cross bar 3. Any pull coming upon the strap, therefore tends to straighten out the strap into one plane and this tendency is resisted by the cross bars 5 and 3 which bind upon the strap. The tongue, therefore, does not bear any of the strain upon the strap or at the most only a very slight amount of the vstrain and, therefore, the tongue will not tear the perforation in the strap. The raised end bar 2 serves as a keeper for the extremity of the free end of the strap.

l of course do not wish to be limited as to the proportions or material employed in constructing the buckles and variations may be made in minor particulars without departing from the spirit of my invention.
